  Crustacea - LoveToKnow 1911
Many, perhaps the majority, of the Crustacea are omnivorous or carrion-feeders, but many are actively predatory in their habits, and are provided with more or less complex and efficient instruments for capturing their prey, and there are also many planteaters.
Perhaps the most important of all Crustacea, however, with respect to the part which they play in the economy of nature, are the minute pelagic Copepoda, of which incalculable myriads form an important constituent of the " plankton " in all the seas of the globe.
In nearly all Crustacea the antennules and often also the antennae bear groups of hair-like filaments in which the chitinous cuticle is extremely delicate and which do not taper to a point but end bluntly.

 CRUSTACEA - Online Information article about CRUSTACEA
General Morphology of Appendages.—Amid the great variety of forms assumed by the appendages of the Crustacea, it is possible to trace, more or less plainly, the modifications of a fundamental type consisting of a peduncle, the protopodite, bearing two branches, the endopodite and exopodite.
The two distal endites are regarded as corresponding to the endopodite and exopodite of the higher Crustacea, the axis or corm of the Phyllopod limb representing the protopodite.
Very few Crustacea are viviparous in the sense that the eggs are retained within the body until hatching takes place (some Phyllopoda), but, on the other hand, the great majority carry the eggs in some way or other after their extrusion.

 LabSpec - Crustacea and Mollusk Allergens
Crustaceans (Crustacea) are classified as arthropods together with spiders (Arachnida), centipedes (Myriapoda), and insects (Insecta).
Crustacea allergens are reported to be heat-stable, water-soluble and can enter the atmosphere in steam aerosols from the cooking process (8,18).
In a study of adult shrimp-hypersentive patients, a common major allergen of 36kd was identified in shrimp (f24), crawfish, crab (f23), and spiny lobster which may explain the clinical histories of patients with immediate hypersensitivity reactions to the crustacea family (12).

They do not have a carapace (the hard covering of the thorax common in other crustacea), and seven (rarely six) of the thoracic segments are distinct and bear leglike appendages.
However, springtails are not crustacea, but insect-like arthropods with only three pairs of legs, one pair of antennae and usually a furcula (a forked structure) on the 4th abdominal segment.
The group of springtails that might be confused with amphipods also has a tubular structure on the last abdominal segment.

 Palaeos Invertebrates: Arthropoda: Pancrustacea
The term Pancrustacea "All the Crustacea" is used to designate the clade uniting insects and Crustacea.
An ironic twist, if this hypothesis does turn out to be true, will be that Crustacea will then become a paraphyletic taxon, and hence invalid under the cladistic system, perhaps to be replaced by a confusing array of smaller clades.
Or insects will have to be called "crustacea", just as many vertebrate paleontology enthusiasts now refer to birds as dinosaurs, thus confusing the fact that birds, while evolving from dinosaurs, really have become a distinct form of animal.

 A CLADISTIC ANALYSIS OF TRILOBITOMORPHA TO CHELICERATA AND CRUSTACEA   (Site not responding. Last check: )
The Chelicerata, Crustacea, and Trilobitomorpha were analyzed cladistically in order to determine whether the Trilobites are more closely related to the Chelicerates or to the Crustaceans.
The results observed from the phylogram show that the Trilobitomorpha are more closely related to the Crustacea than the Chelicerata, which supports Margulis and Schwartz’s (1998) classification.
The Trilobites, the Crustaceans, and the Chelicerates are all grouped in the phylum Arthropoda, which are believed to have evolved from annelid ancestors.

 Checklist of the Collembola: Are Collembola terrestrial Crustacea?
Arthropoda = Chelicerata + Mandibulata (Crustacea + Atelocerata (Myriapoda + Hexapoda)) according to Snodgrass, 1938; Weygoldt, 1979; Wågele, 1993; Wheeler et al., 1993; Wheeler, 1995, 1998 (cited from Giribet and Ribera, 2000:205).
Arthropoda = (Chelicerata + Myriapoda) + Pancrustacea (Crustacea + Hexapoda) according to Turbeville et al., 1991; Friedrich and Tautz, 1995; Giribet et al., 1996 (cited from Giribet and Ribera, 2000:205); Dove and Stollewerk, 2003.
The differentiation of the alimentary canal seems to relate the Collembola fairly closely to the conditions seen in Crustacea, where a gizzard in the form of a gastric mill is demarcated by cardiac and pyloric valves and a filter.

 The Marvels of Crustacea
The crustacea are particularly interesting to me so I have been focusing on them over the past few months.
One nice thing about observing crustacea is that they are quite transparent (except ostracods) and so I can see what is going on inside of them.
The crustacea are a most interesting group, and play a major part in food chains.

 On the Origin of the Geographical Distribution of Crustacea, by James D. Dana   (Site not responding. Last check: )
With regard to the second head, migration, we should remember, that Crustacea are almost wholly maritime or marine; that marine waters are continuous the globe around; and that no sea-shore species in zoology are better fitted than crabs for migration.
The currents of the oceans favour it, the temperature of the waters is congenial through all this range, and the habits of many Crustacea, although they are not voluntarily migratory, seem to admit of it.
The continental species of Crustacea from the interior of different continents are not in any case known to be identical; and it is well understood that the zoological provinces and districts of the land are of far more limited extent than those of the ocean.
